Abstract
A trailer-coupling assembly is described for securing a trailer to a two-wheel vehicle. The trailer-coupling assembly is rigidly fixed to a rear-wheel frame of a two-wheel vehicle and the utility bed of a trailer. The trailer-coupling assembly is comprised of three joints that each rotate about three separate cardinal axes, permitting the trailer to navigate rough terrain without transferring rotational loading to the two-wheel vehicle. Each joint is configured to rotate at least 90 degrees in a clockwise direction and an anti-clockwise direction about a cardinal axis, providing the trailer-coupling assembly with flexibility to navigate the two-wheel vehicle and trailer over various grades of rough terrain.
Claims20
A trailer-coupling assembly for securing a trailer to a two-wheel vehicle, comprising:
- a first lug component that is rigidly fixed to a rear-wheel frame of the two-wheel vehicle;
- a first link member that is connected to the first lug component at a first joint, the first joint permitting a first rotation about a first cardinal axis;
- a second link member that is connected to the first link member via a second joint, the second joint permitting a second rotation about a second cardinal axis that is orthogonal to the first cardinal axis;
- and
- a third link member that is connected to the second link member via a third joint, the third joint permitting a third rotation about a third cardinal axis that is orthogonal to the first cardinal axis and the second cardinal axis;
- and
- a hitch-connect member that is rigidly fixed to the third link member, the hitch-connect member being further rigidly fixed to the trailer.
A trailer-coupling apparatus, comprising:
- a first joint that is configured to attach a first lug component to a first link member, the first lug component being rigidly attached to a rear-wheel frame of a two-wheel vehicle, the first joint permitting a first rotation about a first cardinal axis that is colinear with a longitudinal axis of the first link member;
- a second joint that is configured to attach the first link member to the first link member, the second joint permitting a second rotation about a second cardinal axis that is orthogonal to the first cardinal axis;
- and
- a third joint that is configured to attach the second link member to a third link member, the third link member being rigidly fixed to a hitch-connect member that is further rigidly fixed to the trailer, the third joint permitting a third rotation about a third cardinal axis that is orthogonal to the first cardinal axis and the second cardinal axis.
A trailer-coupling for securing a trailer to a two-wheel vehicle, comprising:
- a first lug component that is rigidly fixed to a rear-wheel frame of the two-wheel vehicle;
- a first link member that is connected to the first lug component at a first joint, the first joint permitting a first rotation of at least 90 degrees in a clockwise direction and an anti-clockwise direction about a first cardinal axis;
- a second link member that is connected to the first link member via a second joint, the second joint permitting a second rotation of at least 90 degrees in a clockwise direction and an anti-clockwise direction about a second cardinal axis;
- a third link member that is connected to the second link member via a third joint, the third joint permitting a third rotation of 360 degrees in a clockwise direction and an anti-clockwise direction about a third cardinal axis;
- and
- a hitch-connect member that is rigidly fixed to the third link member, the hitch-connect member being further rigidly fixed to the trailer.
